Ruby 如何在RSpec mock_模型中正确地包含和测试ActiveSupport:：Concern？

我试图通过将模块包含在基本的mock_模型对象中来规范模块。但是，当我调用模块中定义的实例方法时，ActiveRecord会尝试与数据库建立连接

模块：

module Stuff
    module SoftDelete
        extend ActiveSupport::Concern

        def soft_delete
            puts "Called here"
        end
    end
end

规范：

describe Stuff::SoftDelete do
    class Network < ActiveRecord::Base
        include Stuff::SoftDelete
        attr_accessor :deleted_at
    end

    before (:each) do
        @network = mock_model(Network)
    end

    context "When a record is deleted" do
        it "is marked as deleted" do
            @network.soft_delete
        end
    end
end

description Stuff:：SoftDelete do
类网络

运行此规范时，出现以下错误：

  1) Stuff::SoftDelete When a record is deleted is marked as deleted
     Failure/Error: @network.soft_delete
     ActiveRecord::ConnectionNotEstablished:
       ActiveRecord::ConnectionNotEstablished
     # ./spec/apoc/soft_delete_spec.rb:18:in `block (3 levels) in <top (required)>'

1）Stuff:：SoftDelete删除记录时会标记为已删除
失败/错误：@network.soft\u删除
ActiveRecord:：ConnectionNote已建立：
ActiveRecord:：ConnectionNotEstablished
#./spec/apoc/soft_delete_spec.rb:18:in'block（3层）in'

注意：如果我在真正的ActiveRecord类中包含SoftDelete模块，它将正常工作。mock_模型似乎无法处理该模块

我想在这件事上帮点忙。

你信任ActiveRecord吗？如果是这样，不要从中继承；单独测试您的模块。如果您的模块包含调用ActiveRecord方法，则将它们存根并仅测试代码
